freezes at zero degrees celcius, boils at 100 degrees celcius.
It is a liquid. Individual molecules bound by hydrogen bonding- this causes surface tension. Has a bond angle of 104.5 degrees. The water molecule is symetriacal. Hydrogen- oxygen bonds are covalent.
chemical formula= H2O
Has an atomic weight of 18. Density of 1kg/cubic meter.

I'm not sure what kind of properties you need but anyways
- water can be in gas, liquid, solid form
- it's compose of oxygen and hydrogen
- its solid form is less dense than it's liquid form, highly unusual
- it is polar
- it has hgih freezing point and low boiling point
- it's an inorganic compound
- it has adhesion, cohesion and surface tension
- it's a extremely good solvent
- it's a crucial part in breaking and forming molecules (dehydration synthesis, and hydrolysis)
- it can be break into two parts, h and oh

1 absorbers infrared radiation
2 a good solvent of many substances
3 has cohesion properties
4 has adhesion properties
5 has the second largest specific heat capacity
6 has a high heat of vaporisation

-at least i didn't cut and paste mine, some people are so lazy!! they should really check before they paste, two of the long winded answers above talk about the 'diagram to the right' - you plebs!

Water's Physical Properties:
Water is unique in that it is the only natural substance that is found in all three states -- liquid, solid (ice), and gas (steam) -- at the temperatures normally found on Earth. Earth's water is constantly interacting, changing, and in movement.

Water freezes at 32o Fahrenheit (F) and boils at 212o F (at sea level, but 186.4° at 14,000 feet). In fact, water's freezing and boiling points are the baseline with which temperature is measured: 0o on the Celsius scale is water's freezing point, and 100o is water's boiling point. Water is unusual in that the solid form, ice, is less dense than the liquid form, which is why ice floats.
Water has a high specific heat index. This means that water can absorb a lot of heat before it begins to get hot. This is why water is valuable to industries and in your car's radiator as a coolant. The high specific heat index of water also helps regulate the rate at which air changes temperature, which is why the temperature change between seasons is gradual rather than sudden, especially near the oceans.
Water has a very high surface tension. In other words, water is sticky and elastic, and tends to clump together in drops rather than spread out in a thin film. Surface tension is responsible for capillary action, which allows water (and its dissolved substances) to move through the roots of plants and through the tiny blood vessels in our bodies.

Here's a quick rundown of some of water's properties:
Weight: 62.416 pounds per cubic foot at 32°F
Weight: 61.998 pounds per cubic foot at 100°F
Weight: 8.33 pounds/gallon, 0.036 pounds/cubic inch
Density: 1 gram per cubic centimeter (cc) at 39.2°F, 0.95865 gram per cc at 212°F

Water's Chemical Properties:

water's chemical description is H2O. As the diagram to the left shows, that is one atom of oxygen bound to two atoms of hydrogen. The hydrogen atoms are "attached" to one side of the oxygen atom, resulting in a water molecule having a positive charge on the side where the hydrogen atoms are and a negative charge on the other side, where the oxygen atom is. Since opposite electrical charges attract, water molecules tend to attract each other, making water kind of "sticky." As the right-side diagram shows, the side with the hydrogen atoms (positive charge) attracts the oxygen side (negative charge) of a different water molecule. (If the water molecule here looks familiar, remember that everyone's favorite mouse is mostly water, too).

All these water molecules attracting each other mean they tend to clump together. This is why water drops are, in fact, drops! If it wasn't for some of Earth's forces, such as gravity, a drop of water would be ball shaped -- a perfect sphere. Even if it doesn't form a perfect sphere on Earth, we should be happy water is sticky.

Water is called the "universal solvent" because it dissolves more substances than any other liquid. This means that wherever water goes, either through the ground or through our bodies, it takes along valuable chemicals, minerals, and nutrients.

Pure water has a neutral pH of 7, which is neither acidic nor basic.

H2o is the most simple of chemical compounds. It is a combination of two of the most common elements in the world and it does not behave like it should.

By the way:
1 gallon = 4 quarts = 8 pints = 128 ounces = 231 cubic inches
1 liter = 0.2642 gallons = 1.0568 quart = 61.02 cubic inches
1 million gallons = 3.069 acre-feet = 133,685.64 cubic feet
